My experiences writing install scripts and the like for a commericial
facsimile subsystem make me appreciate the SysV-style /etc/rc?.d
startup scripts.
Instead of trying to edit rc.local and hoping that the fax daemons
would be started at the appropriate place, I could drop in a script
into /etc/rc3.d/S99unifax and *know* that it would be one of the last
things started as the system was brought up multi-user.
Likewise, the uninstall script was also much easier.
